Question

In which case does the hydrometer sink more? In liquids of greater density or those with a lower density? ​

Answer 1

Answer:

The hydrometer floats higher in denser liquids than in less dense liquids. It is heavier at its bottom end so that the upright position is stable, and a scale in the top stem permits direct density readings. The volume of water displaced is equal to the volume, V, of the crown.
